Abstract
A system encoding and decoding video using intra prediction that uses an edge based determination technique together with smoothing filters.
Claims24
A decoder for decoding video comprising:
- (a) said decoder decoding a block of video frame received in a bit stream based upon other blocks of said video frame without using blocks of other frames;
- (b) said decoding based upon a directional prediction index received in said bit stream using a technique that is dependent on the size of said block;
- (c) wherein said index selectively indicates one of (1) a first technique based on non-filtered received pixel values;
- (2) a second technique based upon a first smoothing filter;
- and (3) a third technique based upon a second smoothing filter;
- (d) wherein said first smoothing filter and said second smoothing filter are based upon an edge determination.
